Mi hermana deposita cheques y ahorra tanto como yo.

Deposita is the third-person singular present tense of depositar.

So it can mean:

• she deposits
• he deposits
• you deposit (formal usted)

In this sentence, because the subject is mi hermana, it means she deposits.

In modern Spanish, possessive adjectives like mi, tu, su, nuestro normally go directly before the noun:

• mi hermana
• tu casa
• su trabajo

English speakers sometimes wonder about this because Spanish often uses articles, but with basic possessives, you usually do not add el/la before the noun.

Spanish often leaves out the article when talking about things in a general, non-specific way.

So deposita cheques means she deposits checks in general, not a specific known set of checks.

Compare:

• deposita cheques = deposits checks
• deposita los cheques = deposits the checks

So the version in the sentence sounds natural if you are speaking generally about what she does.

Because in Spanish, the k sound before e or i is usually written qu.

So:

• que
• quien
• cheque

The plural is cheques.

This follows normal Spanish spelling rules. Even though the word ultimately comes from English check, Spanish adapts it to its own spelling system.

Ahorra is the third-person singular present of ahorrar, which usually means to save, especially to save money.

In this sentence, it appears without a direct object, and that is completely normal. Spanish can use ahorrar intransitively, like English to save:

• Ella ahorra. = She saves.
• Yo ahorro mucho. = I save a lot.

So ahorra here means something like saves money or simply saves.

Tanto como is a comparison structure meaning as much as or as ... as, depending on context.

Here it compares the verb ahorra with yo:

• ahorra tanto como yo

That means she saves as much as I do.

A useful way to think about it is that Spanish often leaves out the repeated verb when it is obvious:

• Mi hermana ahorra tanto como yo ahorro.
• shortened to: Mi hermana ahorra tanto como yo.

Both express the same idea, but the shorter version is more natural.

Because the sentence is really short for:

• Mi hermana ahorra tanto como yo ahorro.

The pronoun is functioning like the subject of the omitted verb ahorro, so Spanish uses yo, not mí.

Compare:

• como yo = as I do
• para mí = for me

English speakers often expect an object pronoun after a preposition, but in this kind of comparison, Spanish uses the subject pronoun.

Because here tanto is modifying the verb ahorra, not a feminine noun.

When tanto is used with verbs, it stays invariable:

• trabaja tanto como yo
• come tanto como tú
• ahorra tanto como yo

But when it modifies a noun, it agrees in gender and number:

• tanto dinero
• tanta paciencia
• tantos libros
• tantas horas

So in this sentence, tanto is correct because it refers to how much she saves.

Because Spanish, like English, does not need to repeat the subject when the same subject does two actions in a row.

So:

• Mi hermana deposita cheques y ahorra...

means:

• My sister deposits checks and saves...

The subject mi hermana applies to both deposita and ahorra.

Repeating it would sound unnecessary unless you wanted special emphasis.

Yes, but the meaning shifts a little.

• tanto como yo emphasizes quantity/degree: she saves as much as I do.
• igual que yo often means the same as me / like I do, which can sound a bit broader or less specifically about amount.

For saving money, tanto como yo is the more precise choice if you want to compare how much.

Yes, depositar cheques is standard and widely understood.

That said, vocabulary can vary by country. In some places, banking language may use other verbs in certain contexts, but depositar is a very common and safe choice across Latin America.

So for a learner, depositar cheques is a perfectly good expression to know.

A few pronunciation points matter here:

• The h is silent
• The rr is a strong rolled/trilled r
• The stress is on the middle syllable: a-HO-rra

A rough guide would be:

• ahorra ≈ a-O-rra, with a rolled rr

This is different from ahora, which means now and has only one r.

So:

• ahorra = saves
• ahora = now

That pair is very important to distinguish.

Yes, grammatically you can, and it is understandable.

But Spanish usually prefers the shorter version:

• Mi hermana deposita cheques y ahorra tanto como yo.

The verb ahorro is omitted because it is already clear from the context. This kind of omission is very common and natural in Spanish comparisons.
